摘要

Dental chair (1) comprises a base (2), a height-adjustable seat (7), and a drive (4) for adjusting the height of the seat. An adjusting mechanism (9) arranged between the base and a support part (8) for the seat is designed so that when the seat is raised by the drive it also tilts relative to the base. Preferred Features: The adjusting mechanism consists of a four-bar linkage. The distance between the fixing points of the adjusting mechanism on the base is greater than the distance on the support part. The levers of the adjusting mechanism are different lengths. The seat tilts by about 10 deg when raised from the base position to the highest position.
